Integration with ePR appointments (EMIS in my case)

We add triaged Patchs to specific users' EMIS appointments (users always start their workflow from EMIS appointments) Once we have allocated a Patchs to a user we want the system to book an appointment for that user in that session (or 'pre-book' by selection) in EMIS to save a manual process. (as you have self-booking functionality we imagine you have the correct API for this?). This would speed up our triage workflow and also reduce the occasional error (of omission or mis-booking in the heat of the moment).
